Product overview
Over the years, fiber-based access has proven to be a cost-effective way to reach customer premises to deliver managed business and residential services. Ethernet or Passive Optical Network (PON) technologies such as Gigabit PON (GPON) are supported by FS OLT/ONU. PON modules support fiber-based (FTTx) access scenarios, including Fiber To The Home (FTTH), Fiber To The Building (FTTB), Fiber To The Curb (FTTC), FiberToThe cell (FTTc), and Fiber To The Business (FTTb).
